What are the basic properties of hydrogen?
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen.
Nov 20, 2020 · Boiling point of Hydrogen is -252.9°C. Note that, the boiling point associated with the standard atmospheric pressure. In general, boiling is a phase change of a substance from the liquid to the gas phase.
The curve between the critical point and the triple point shows the hydrogen boiling point with changes in pressure. It also shows the saturation pressure with changes in temperature. At the critical point there is no change of state when pressure is increased or if heat is added.
It's only thanks to a special trick of hydrogen's that we can use water at all. Hydrogen forms weak bonds between molecules, latching onto adjacent oxygen, nitrogen or fluorine atoms. It's these hydrogen bonds that give water many of its properties. If they didn't exist, the boiling point of water would be below -70 degrees Celsius.
The curve between the critical point and the triple point shows the hydrogen boiling point with changes in pressure. It also shows the saturation pressure with changes in temperature.
Jun 27, 2024 · The two forms of hydrogen have slightly different physical properties. The melting point of para-hydrogen is 0.10° lower than that of a 3:1 mixture of ortho-hydrogen and para-hydrogen.
